CURTAIN-FIXTURE.

SPECIFICATION forming part of Letters Patent No. 252,359, dated January 17, 1882.

Application filed May 19, 1881. (No model.)

To all whom it may concern Be it known that we, JOSEPH DARLING and ANDREW J. NICHOLSON, citizens of the United States, residing at Peachville and Fairview, respectively, in the county'of Butler and State of Pennsylvania, have in vented certain new and useful Improvements in Uurtain Fixtures and we do hereby declare the followin g to be a full, clear,and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompan yin g drawings, and to letters or figures of reference marked thereon, which form apart of this specification. g I

Our invention relates to improvements in curtain-fixtures in which the end of the roller carrying the curtain or winding pulley is provided with a series of teeth or pallets, between which the end of a pawl can enter and find lodgment until displaced by pulling upon the cord'of the fixture; and the objects of our im provementsare to dispense with springs or loaded tassels, to afford facilities for the proper adjustment of the rollers sustaining-cords and prevent the marring or indenting of the window-casing by the rollers fixture while sudits support.

denly stopping the curtain in its descent.

The invention will first be described in connection with the drawings, and then pointed out in the claims.

In said drawings, Figure 1 represents in perspective our curtain-fixture attached to a window-casing. Fig. 2 represents in perspective the end of the curtain-roller carrying the ratchet-wheel and spool. Fig. 3 is an end view of the same. Fig. 4 is a perspective view of the movable fixture or pawl, from which the spool end of the curtain-roller is to be suspended. Fig. 5 is a front view of the same. Fig. 6 is a vertical section of the pulleys used to elevate the curtain-roller, and other accessories secured to the window-casing. Fig. 7 is a perspective view of the pulleys carrying ratchet-pallets, and detached from the casing. Fig. 8 is a perspective viewof the pawl and Fig. 9 is a perspective view of the parts forming the curtain-roller spool.

In said drawings, A represents the window frame creasing.

B represents a window-curtain part] y wound upon a roller, This roller is provided with metallic caps c and c. The latter cap carries a I spool, 0 upon which is wound the cord 0 in opposite direction of the curtain B. This spool 0 can be made in two parts, as shown in Fig.

9. The spurs 0 passing through the openings I 0 enter the wood of the roller and preventits twisting off. The roller 1) carries at that end a headed spindle or screw, 0 upon which it can revolve. The outer side or septum of the spool c is provided with a series of radial pallets, c, to arrest the rotation of the roller when they come in contact with the pawl d, projecting from the inner side of the movable bracket D. This bracket is formed of a metal disk,

from which extends in the same plane an arm, D, to which is secured the cord E, used to suspend it. The bracket D has also another arm, D extending at right angle with the inner face thereof. This arm D is slotted horizontally to receive the cord 0 of the curtain-rollers spool, and is controlled thereby.

The bracket D is provided with an angular slot, large enough at its upper end, d, to receive the head of the spindle 0 while its lower end, 6?, is of smaller size to receive the neck only, or the portion under the head of the spindle. The slot d assuming a nearly horizontal position when in use, the head of the spindle willretain the bracket in close contact with closed in a short rubber sleeve, 0, extending i above its upper end, to keep the window casing from becoming bruised or' indented when the curtain is suddenly arrested in its descent by the pawl d becoming engaged with the ratchet on the end of the roller, causing the arm D to assume for an instant a nearly horizontal position.

The curtain is wound upon its roller by a steady pull upon the cord 0 as it throws the pawl d on the outside of the path of the pallets c. 'When it is desired to arrest the curtain at any desired height the cord 0 is suddenly released, causing the curtain-roller to slightly IOC unwind itself, and. rotating its spindle toward the center of the bracket D or its pawl d, and, bringing the latter in the path of the pallets suddenly arrests the unwinding of the curtain.

To elevate the curtain-roller at any desired height, and to raise both ends thereof uniformly and retain them permanently, there is secured to one side of the window-easing and near its top a series of pulleys, g g 9 united together and capable of rotating upon a sleeve, it, through which passes the fastening-screw h. The outer pulley, g, is to receive one portion of the cord E, that passes over the button f, and has that end secured to the movable bracket D. The cord is then passed through aholein the septum of the pulley and partly wound around the pulley g, and its pendent end E is provided with a link, 2', to embrace the neck ofthe headed spindle secured to the corresponding end of the curtain-roller.

To the pulley is secured one end of the cord G, used to revolve the three pulleys, being for that purpose coiled a few turns around said pulley g. The septum of said pulley is provided with a series of radial pallets, g, to arrest its rotation when coming in engagement with the projecting tooth l on the side of the pawl L. This pawl is pivoted at m to aplate, n,provided with spurs n, to retain it in connection with the sleeve hand screw h, immovably secured to the casing A. The pawl L has a large opening or slot, 1, in the center thereof, for the free passage of the sleeve h. It is also provided on one side with a slotted arm, L, for the passage of the controlling-cord G. To elevate the curtain-rollerat both ends, the cord Gris pulled upon, which depresses the arm L of the pawl and elevates the tooth l thereof out of the path of the pallets g and allows the pulleys g g g to rotate. \Vhen the cordGr is released the pawl L partially revolves around its pivot m, and its tooth l enters into engagement between the pallets and prevents any further motion of the pulleys g'g g and thus the curtain-roller is suspended evenly and securely at any desired height.

We are aware that curtain-rollers have been suspended from the ends of a single rope, and do not claim, broadly, that mode of suspend- 5o ing curtains.

Having now fully described our invention, we claim- 1. In combination with awindow-casing and a curtain-roller suspended from the ends of a single cord, the three pulleys g g 9 united and adapted to turn together-upon a si gle shaft or sleeve, with the cords E, E, and Gr, substantially as and for the purpose described.

2. The combination of perforated plate n and pawl L, slotted at l,-and pivoted on a pin,

m, having its axis at right angle with the axis of the curtain-roller, and provided with a tooth,

l, at the upper edge thereof, and a slotted arm,

L, with pulleys g gv {1 carrying pallets 9 substantially as and for the purpose described.

The combination of a curtain -roller, a spool at the end thereof having projecting pal lets c and spindle 0 with movable bracket D, having pawl d projecting therefrom, arm D above, and arm D in front thereof, substantially as and for the purpose described.

4. In combination with the movable bracket D, having a pawl projecting therefrom, abent arm, D and an arm, D, from which it is suspended by a cord, the yielding sleeve 6, inclos ing the upper arm, D, substantially as and for the purpose described. I

5. The combination of a curtain-roller, acord connected at both ends to said roller and between said ends to the septum of a pulley, a series of pulleys upon the same axle, the inner pulley having pallets projecting from its septum, and a slotted pawl pivoted to a plate clamped to the side of a window-casing, substantially as and for the purpose described.
